I'm curious as to why there is so little reloading info in the reloading books on the 55 and 62 grn FMJ bullets, especially the 62's

So many people shoot them and most books don't even mention the 62's so you have to look at the 60"s and 63 grn loadings, look at the length of the bearing surface of the bullet as that has a big effect on pressure, then work up your own loads from there.

it would be really nice to see more info, especially on the 62's.

I've been reloading for 35 years, so I can hit it fairly close without getting into overpressure loads just from experience, but for the guy just starting out, it sure would be nice to have a good refernce.

Anybody got some good loads for the .5.56 with the SS109 62"s???
They have a longer bearing surface than most 62's and are never all that accurate due to their construction anyway.

Thanks, I've had good luck with the 4895. My gun seems to hate the H335.
I have not found a good load with it yet for my rifle. Every rifle is different.
I want to experiment with the AA2230 more, it's shot very well in my rifle as have the IMR 8208 XBR. The X Terminator has been so so, but I'm not giving up on it yet. Tac is decent with heavier bullets.

I'm really looking to see what others have loaded the SS109's at. They do have a long bearing area compared to other 62's, so they will generate higher pressure with a similar load in a standard FMJ.
They are not known for being real accurate due to the insert anyway.
Thank you for your reply, anybody else have any good loads?

I think you will like the 2230 powder, I've been using it now for awhile, and for reloading data I use the Lee Modern Reloading Manual,(there are 22 loads just for 55 gr alone) . It has one of the biggest and best compulations of data out there, not limited to one or two powders or projectiles. I use it to reload all of my rounds, but I also use some of the others manuals out there as well

What other 62gr bullets do you have in mind?
I ran some numbers on QL with the SS109 and Speer 62gr 1050 and a Max load of Tac. As you can see the Speer 62gr generated more PSI than the SS109.

Thank you Steve.
The one really neat thing about the Tac powder is that it has much lower pressure vs the FPS it produces than other powders do. For that reason, the higher to max loads of Tac don't worry me as much when it comes to high pressure.
It's a really neat powder if you find a load that shoots well in your rifle with it.

I have tried the Tac with the 69's, but not the 62's. I better get on the ball.

I just got a Crony with the printer, I'm really looking forward to the data that I get from it.
Having a cronograph is almost a necessity when working up loads and figuring bullet drop.
You can find out a lot about your loads shooting over the screens.

Very good info. I have not seen the BC numbers on the SS109's, they just look longer than most and I'm not sure if the bearing area is longer or just the ojive. I'm thinking it's just a longer ojive.

Nobody around here uses Varget, huh?
After a couple of months "playing" we've finally nailed down the bullets for our .223's.
Oddly enough, mine seems to really like the 69 MK's- then nothing else down to 52 Nosler Competitions. The Noslers grouped pretty well, but POI was waaayyy left and low. Same promise showed with 82 gr. match Bergers (single loaded), but again POI way off.

Now it's time to play with powders I guess...

Seems though, that once you've got it down to the "best", that's all you're going to want to shoot because changing means re-zeroing the scope. Or, do you guys never stop- and constantly try something different in search of some magic combination?

My heavy barrel AR shoots 69gr and 52gr MK's, nothing in-between. The 1/9 twist just doesn't group well with 55gr bullets. Powder was 4064, Varget or military pull down 4895 with a 4064 burn rate.
Guys with their match bolt rifles would see my targets and shake their heads in disbelief.
